  • the displacement means allows a defined relative movement of the mounting bracket counter to the direction of travel to the rear.
  • the cross member which deforms as a result of the accident, presses against the mounting bracket or its superstructures.
  • the mounting bracket according to the invention can escape to the rear or shift to the rear, without its attachments are damaged.

  • the guide slot may preferably be a slot, the z. B. mounting carrier side or body side is provided.
  • the above-mentioned counter-element that is the bolt, be guided and screwed with a predetermined torque with the longitudinal guide element.
  • the screw torque is designed so that at a collision impulse of the mounting bracket along the slotted guide is displaced to the rear.
  • the cross member may be connected via deformation elements arranged on both sides in the vehicle transverse direction as well as via bulkhead plates connected thereto with vehicle side members.
  • the mounting bracket may preferably be arranged behind the deformation elements of the cross member via the displacement means, viewed in the direction of travel.
  • the displacement means may be connected to the bulkhead plates between the cross member and the side rails.
  • the cross member deforms in the direction of the mounting bracket and pushes this also opposite to the direction of travel to the rear.
  • the mounting bracket is thereby shifted relative to the stationary bulkhead plates to the rear.
  • the displacement means may be formed in a particularly preferred manner by both sides between the cross member and the mounting bracket, in itself dimensionally stable displacement slide. These may optionally be formed directly on the mounting bracket.
  • the displacement means may be fastened to the mounting carrier and in each case connected to the cross member via at least one resilient connection defined in the vehicle longitudinal direction. This also allows a problem-free replacement of the sliding carriage, possibly after a crash event.
  • the approximately vertically oriented screws of the screw each project through the aligned in the direction of travel slot in the center shift I.
  • the screw is structurally designed so that at defined impact forces yields the positive connection and the sliding carriage can shift over the length of the elongated hole to the rear.
